The fiber core 丨〇2 of the first connector 光纤3 of the optical fiber is inserted into a guide bow groove 65 by the lower portion of the pressing portion 66 of the holder 6, and will be from the rear side of the guide groove 05. The end pulls back. In the attaching operation of the holder 6, the hook portions 64a formed on the front surface of the holder 6 are hooked to the pushing portion 17 (the body is formed on the lower side end of the supporting fishing rod 7a). The hook portion 64b on the rear side surface of the hook portion 64a is hooked to the support groove 17a, thereby maintaining the hook of the hook portion 64a. The state is attached to the rear side portion Π d of the connector body 1. In the winding step of pulling the optical fiber cable 1〇〇 back to the reel 5 by the holder 6 guiding the groove 65, the leading end of the optical fiber cable 1 〇〇 cladding layer (! The end portion of the covering layer is fixed between the outer circumferential surface of the winding body 50 and the protruding portion 53, 53 (the covering fixing portion), and the core wire 102 of the optical fiber is located through the protruding portion a portion between the portion 5 3 and the pulling wall 5 6a or 5 6b is introduced into the winding portion between the flange 51 and the flange 52, and the anger line 102 of the optical fiber is wound around the winding. Partially. This winding step is performed by a grip 58 formed on the front side surface 20 1262332 of the winding body 5 that is held by hand. This winding operation can be performed simply.

When the remaining length of the optical fiber core 1 〇 2 is short, after the core wire 102 of the optical fiber passes through the pulling groove 57 and is pulled from the space between the protruding portion 5 4 and the pressing portion 55 to the outside, The cord reel 5 can be inserted into the receiving portion 62 of the holder 6 and fixed in the holder 6, as shown in Figs. 8A and 8B. In addition, after the cord reel 5 is inserted, the grip 5 8 can be guided by hooking with the guiding groove 63 in the side wall 61 1 a of the holder 6 to easily the reel 5 The holder 6 is inserted and can receive the reel 5 and fix it in the normal direction in the receiving portion 62. In addition, the reel 5 is received and fixed in the normal direction, so that the front end of the pulling groove 57 and the rear end of the guiding groove 65 of the holder 6 communicate with each other, thereby The pulling groove 57 and the guiding groove 65 form a guiding path for guiding the core wire 102 of the optical fiber. Further, after the reel 5 is inserted until the lower edge of the winding main body 50 in the receiving portion 62 contacts the stepped portion 61d of the inner side surface of the side wall 61b, the hooking recess 5 of the front side of the winding main body 50 9 hooks to the side wall 61 1 a hook projections 6 8 to prevent the cord reel 5 from being pulled out. In addition, when the hook on the side wall 61 1 a is hooked to the hook recess 5 9 , the elastic force of the side wall 6 1 a and the inclination of the lower side of the hook recess 5 9 can be utilized. The hooking step is performed simply on the surface. Further, after the cord reel 5 is fixed to the holder 6 attached to the connector body 1, the holder 6, the rear side portion of the connector body 1, and the optical fiber cable 1 can be 〇 The remaining portion of the cover layer 1 of the crucible 1 is received in the take-up box 91 (refer to FIG. 9A), and the upper side 21 1262332 of the mounting frame 8 can be utilized.

And an elongated hole 84 in the lower side portion, and an attachment bolt (not shown) is fixed to the bolt hole (not shown) of the wire take-up box. The elastic hook portion 7 3 of the device cover member 7 can then be hooked to the hook recess portion 1 2 c of the connector body 1 to attach the decorative cover member 7 to the connector body 1 A side of the front side surface is attached to a front side surface side of the mounting frame 8 by a pinching portion (not shown) or a bolt. The decorative plate 90 can cover the respective attachment holes and the mounting frame 8, and the front side portion of the connector body 1 and the decorative cover member 7 are exposed from an aperture of the decorative plate 90. Out, thus completing the construction work. In this state of construction, in order to minimize the receiving space of the optical fiber connecting device, the connector 3 and the reel 5 are arranged parallel to each other, and the pulling direction of the optical fiber core 102 is upward. The optical fiber core 102 is bent to protrude upward between the connector 3 and the reel 5. Here, the optical fiber core attached to the optical fiber connector 103 is introduced into the winding portion of the reel 5 through the guiding groove 65 of the holder 6 and the drawing groove 57 of the reel 5. However, since the pressing portions 66 and 55 that press the bent portion of the optical fiber core 102 from the upper side are respectively placed on the reel 5 and the holder 6, the bent portion of the optical fiber core 102 can be prevented from expanding toward the upper side (at Keep away from the connector 3 and the direction of the cord reel 5). Further, the remaining length portion of the optical fiber core 102 is placed at a position lower than the pressing portions 55 and 66, so that the optical fiber core 1 2 can be reliably fixed. In the present embodiment, for the expansion suppressing portion, the pressing portions 5 5 and 6 6 are placed at the holder 6 and the reel 5, respectively. However, the pressing portion may also be placed at the holder 6 or the cord reel 5. 22 1262332

Further, as described above, the connector 3 and the cord reel 5 are arranged in parallel to each other in the front-rear direction, and the optical fiber core 102 is bent in an anti-"U" shape therebetween. However, since the radius of curvature of the optical fiber core 102 is greater than the allowable minimum radius of curvature so as not to impair the signal transmission characteristics of the optical fiber cable, it is generally difficult to make the optical fiber connector 103 and the winding portion ( The spacing between the flanges 5 1 and 5 2 is shorter than the length determined by the tolerable minimum radius of curvature. Therefore, in the winding body 50 of the cord reel 5, only after the cladding holder holding the cladding layer 101 is placed on the winding portion around which the optical fiber core 102 is wound At the side (as shown in FIG. 9B), the length of the front side surface of the connector body to the rear side surface of the cord reel 5 can be extended, and only a depth of one standard box can be used in depth as the Closing box 9 1. On the contrary, in the cord reel body 50 of the cord reel 5 according to the embodiment of the present invention, since the cladding holder is placed on the front side (the side of the connector 3 instead of the winding portion), and The cover holder can be placed by the clearance space between the connector 3 and the winding portion, so that the front side surface of the connector body 1 and the rear side surface of the cord reel 5 can be shortened. length. Therefore, a box body which is shallow in depth can be utilized as the take-up box 9 1 . Further, in the state of being constructed, the diameter of the optical fiber core 102 wound around the cord reel 5 incorporated in the receiving portion 62 is widened by the outward elastic force, and will be wound on the optical fiber core 1 02 creates a space between the winding body 50 and the winding body 50. However, as shown in Fig. 10B, in the state in which the cord reel 5 is incorporated in the receiving portion 62 of the holder 6, the clearance between the winding body 50 of the cord reel 5 and the lower side of the receiving portion 62 Space is not 23

When 1262332 is present, the optical fiber core 102 is forced to be removed from the extension to the upper side by the extension. Therefore, the remaining length portion of the optical fiber core that is forced to be removed to the upper side comes into contact with the foreign matter in the take-up box. On the contrary, in this example, the lower semicircular portion of the flange 5 1 of the reel 5 is connected to the step portion 61 d at the inner side surface of the side wall 61 b of the stator 6, and the lower side of the 58 The lower side of the guiding groove 63 can be accessed, so that the device 5 can be received in the receiving portion 6 2 while ensuring the receiving space between the lower portions of the winding body 50 receiving portion 62. Therefore, the remaining portion of the cable can be prevented from being removed to the outside of the receiving portion 62 by pushing the remaining portion of the cable into the receiving space 67. Therefore, the core wire 102 can be reliably protected. According to a first aspect of the present invention, a fiber optic cable is wound around a reel that is larger than a radius of curvature of a minimum radius of curvature, because only the core of the fiber optic cable is wound around the reel. The remainder of the line is easily managed without degrading signal transmission characteristics. Further, in a state in which the cord reel is fixed in the holder, since an expansion unit contacts the bent portion of the core wire, the optical fiber core portion can be prevented from being away from the connector and the reel. The upper is expanded to thereby fix the core of the fiber optic cable. In order to minimize the receiving space of the optical fiber connecting device, the optical fiber device and the reel are arranged in parallel with each other in the front-rear direction, and the core of the optical fiber cable is in the optical fiber connector and the reel The bending of the core wire is required to make the radius of curvature of the core wire larger than the allowable minimum bending path without deteriorating the signal transmission characteristics of the optical fiber cable. Therefore, the printing 62 102 is required to implement the solid grip winding wire and the light portion, the light can be reliably inserted by the core, and the bending force is reliably inserted and the yield is half.

The spacing between the 1262332 fiber plug and the coil in the front-rear direction accommodates the interval determined by the minimum radius of curvature. According to the present invention, in the cord reel, since a fixing portion for fixing the cladding of the optical fiber is disposed at a portion of a fiber optic cable connector, the reel for winding the core wire is arranged relatively far away The portion of the fiber is thus placed between the connector of the fiber and the wire to place the cladding holder. Thereby, the distance between the front side surface of the insertion and the rear side surface of the cord reel can be shortened. Therefore, the reel is received in a space that is shallow in depth. According to a third aspect of the present invention, the cord reel is provided with a grip e that grips the grip to wind the core wire onto the cord reel, which is an effective performance. In addition, since a guiding groove connected to the grip is formed on one inner surface of the receiving portion, the grip is guided in the guiding groove, thereby improving work efficiency, and The receiving step of the reel receiving the receiving portion of the holder is according to the fourth aspect of the present invention, since the receiving space for the optical fiber cable is formed on the bottom side surface of the receiving portion of the holder, even if it is wound around The core wire on the cord reel is stretched to produce a surplus portion, and the remaining portion of the core wire can be prevented from being pulled out from the receiving space by pushing the remaining portion into the joint. The core of the fiber optic cable can be reliably protected. The foregoing description of the various exemplary embodiments of the present invention is not limited to the foregoing exemplary embodiments, and the scope of the claims, the detailed description and the drawings The cover of the state of the cladding, and the connector between the connectors of the connector. The main body' can be used, so that the reeling force of the reel can be increased by the reel of the wire reel. Therefore, the present invention has been modified in the form of various 25 1262332 from the present invention.
